HOW TO setup Host Header Names to Host Multiple
Sites on One IP
Configure Host Header Names in IIS 5.0
To configure host header names in IIS, start the Internet Service Manager (Iis.msc)>the
Properties of the web, select IP address that the site will use and TCP Port
that should be used (usually 80). Click Advanced>Multiple identities for this
Web Site list, select the identity that you want to use. Click Edit, and then
add the desired host header name like web1.domain.com. Register the host header
name with the appropriate name resolution system. If the accessed web is on an
intranet register it with the intranet's name resolution system, such as WINS
and internal DNS. If the access web is on the Internet, register the host header
name with DNS, which is administered by InterNic.
NOTE: If you want this site to respond to more than one host header name, use
the Add button to add additional identities to this list. Specify a different
host header name for each identity, but be sure to use the same IP address and
port.
Multiple Webs Troubleshooting
If you get error:
Event ID : 115
Source : w3svc
Description : The service could not bind instance X.
This problem can occur when some or all of the Web sites that are using Host
Headers have the same port number defined for Secure Sockets Layer (SSL).
Internet Information Server does not support the use of Host Headers for SSL.
